Hey guyz i use to be able to play dvds on my dvd rom perfectly but recently its not working....Well the picture is but teh sound isnt for some reason, i use InterVideo WinDVD 4 and sometimes RealOne Player anyone know wat happened?? Is it that i might have installed a new codec or somethng that is causing htis??? But ofcourse the dvds work perfectly on my standalone dvd player so i know that the dvd does have sound
